Application ined April 30,

IThe invention relates to davenports and more particularly to that type of d'aven'p'ort convertible into a bed. u

rThe object 'of the invention is to simplify and improve upon the type of davenport shown in United States Letters Patent No. 1,349,622, dated September 17, 1920, to

harles WV. Meves and Frederick G. Herrmann, by simplifying the linkage construction for the bed sections and by making the construction so compact that the height of the seat is no greater than that of the usual fixed seat davenport. 4

The invention further' consists inthe Several features hereinafter set forth and more particularly defined by claims at the conclusion hereof. y l

ln the drawings: Fig. lis an end view of a bed davenport embodying the invention, shown in closed position, one end thereofbeing removed; Fig. 2 is a view similar to Fig. l, showing the davenport converted into a bed; Fig. 3 is a detail sectional v'iewtaken on the line 8-3 of Fig. 1; Fig". 4 is ahdetail plan view of a part of the device; Figs." 5 and 6 are views similar to Fig. 1, showing the parts in' intermediate positions. i

n the drawings the numeral 5 designates an end frame, the other Similar end frame not being shown in detail, but both connected to a fixed back 6. A

A pair of plates 7 are preferably detachably connected to the end frames by means of screws 8 or other suitable fastening means. All the moving parts of the davenpo'rt are carried by these plates which may be readily attached to the davenpo'rt. l

A front rail 9 is fixed to the end frames by the plates 7 each of which has a' flange portion 10 secured to the front rail by screws 1 1. A hook-shaped swinging arm- 12 is pivotally mounted at its lower end on a pin 13 secured to each plate adjacent the lower parts of the front rail. y p Y The upper forwardly projecting end of each arm 12 is pivotally connected by a pin le to the frame of the seat member or cushion 15 near the front end thereof. On Vthe pivotal connections thus formed the se'atwinay be inverted from its upright position, shown in 19'2'3. 'Serial No. 635,579.

The seat member lhas links 19`pi`votally secured ,to its framenear its rear end'. bed section 20 is pivotally connected to said' 119: Another bed section 21 its conneeted to the irst bed section 2O through anfinterme'- Y,

support the rear part of the bed when the seat is inverted. y y y,

To hold the hinge links 22 aline-dwitli the adjacent frame members of thebed lsectipn 21k during a part of its movement, each link carries a laterally projecting" arm con; nected to 'one end of a tensioned coil spring the other end of said spring beingfsefcured of said bedV the forward ends of the slots 27, as shown in Fig. 2.

To change the device to its bed form the operator grasps the rear end of the seat and draws it upwardly and forwardly to inverted position. On the first part of the upward movement of the seat member the swinging of the arms 12 toward the front rail brings the hinge links 22 against the plate 85 upon which the links slide upwardly until the front edges'of the arms 12 abut against the front rail. Following this the seat member swings about the then stationary arms and during the first part of this movement the links 22, by the action of the springs 32, straighten out into alinement with the adjacent frame members of the bed section 21 and the bed section moves rearwardly so that the pins 30 are positioned in the forward part of 'the slots 27, as shown in Fig. 5. On the movement from the position shown in Fig. 5 to that shown in Fig. 6, withthe seat slightly beyond the vertical position, the bed section 2l has lifted and moved forwardly relative to the legs 28 to bring the pins 30 to the rear ends of the slots 27, thereupon lifting the legs 28 and effecting theV engagement of their lower edges with the pins 36, which then assume a lifting function and simultaneously move the pins 30 forwardly in the slots 27. During the movement of the seat from the position shown in Fig. 6 to that shown in Fig. 2, the legs 28 are raised to bed-supporting position i and by the action of the pins 36 the free ends of the legs are swung to the forward ends of the slots 27. Simultaneously the bed sections 20 and 21 are swung into alined position parallel to the floor. In this position the bed sections are supported from the seat and the end frames by the links 19, the brackets 24, and the legs 28. The usual folding legs 36 on the seat are swung down to supporting position to prevent tipping of the bed.

To return the parts to closed position the movements of the seat member are reversed and the bed sections are swung into the position shown in Fig. 1 with the rear portions of the seat resting on the ledges'l and the arms 12 abutting the stop pins 16. Duringthis closing movement the legs 28 swing down against the stops 33 as the seat member swings about the arms 12, and further swinging movement of theV seat member brings the y Lipper portionsof the hinge links 22 into sliding contact with the front rail and the continued movement of said seat member swings them out of line with the bed section 2O and to the position shown in Figyl, the pins 30 moving in the slots 27 to accommodate these movements.

It will be noted that the arms 12 swing forward as the seat section is raised into abutting engagement with stops, which in the present instance are the flanges l0 on the plates, and at this time the pivotal connections between the seat and the forwardly projecting portions of the arms have been moved far enough in front of the front rail to permit inversion of the seat without interference with the front rail. This feature is important and an improvement over the structure shown in the patent previously referred to because it obviates the use of slots between the front rail and the end frames and thereby greatly strengthens the constructionr and makes it simpler and easier to assemble. It is not necessary that the hinge section 22 ride on the front rail but by employing this feature the parts may be more compactly folded together and the swinging arms may be brought close to the front rail.

The desirability and functions ofv the engagement of the hinge section 22 with the front rail, and also of the lost motion between the rear end of the bed section 2l and the end frames, will be apparent from an inspection of Figs. 5 and 6. It will be seen that while the hook-shaped arms 12 remain in engagement with the front rail, the pivotal connection 23 between the seat and the hinge portion 22 traverses a circular path about a fixed center. During the closing movement of the seat it is necessary to break the joint between the hinge section 22 and the rear bed section 21, and this is accomplished by providing a reaction support for the forward end or" the hinge section, about which the hinge section may swing downwardly upon the descent of the bracket 2li, which latter then exerts a lateral pressure on the hinge section. The hinge joint is thus effectively broken without subjecting it to unnecessary stress in the plane of the bed frame members. The direct imposition of a lateral pressure on the oint inorder to break the joint is particularly desirable when the joint members are urged into alignment by constantly acting means, such as springs. ln the present instance, the top edge of the front rail forms a convenient reaction support and the sliding engagement of the hinge section thereon permits both the rotation and translation of the hinge section, particularly during the closing movement of thefdavenport, but also during the opening movement.l straining the movement of the linkage in this manner, it is also possible to secure greater compactness of construction than would otherwise be feasible.

The lost motion connection between the rear end of the bed section and the end frames is provided to insure the smooth working of the linkage without anyv tendency toward binding, particularly when the bed sections and the legs 28 approach parallelism. As

Bv conaligned position, it will be evident that the hinged connections between them and between the bed section 21 and legs 28 would be subject to severe pressures in the plane of the bed section if the rear end of the bed section 2l were not free to move with respect to its connection with the end frames. rl`he pinand-slot connection, in addition to affording a linkage that operates smoothly, rapidly and positively, also permits greater compactness than would be otherwise possible. 'lhe pin-and-slot connection is effective to insure smooth operation during the folding and unfolding operations of the davenport but rendered ineffective to permit relative movement in the bed-forming position of the davenport, as shown in Fi 2, by the locking pin 36, which retains the ed supporting leg in a definite supporting position at one end of the slot 27.

I/Vith the construction above described such a compact arrangement is provided to keep the height of the seat within the limits usually employed on unconvertible davenports.

I desire it to be understood that this invention is not to be limited to any specific form or arrangement of parts except in so far as such limitations are specified in the claims.
